Swearing can make you strong.
MUSCLE strength and stamina can be boosted by swearing, a study has found.
Psychologists conducted tests in which volunteers had to swear before intense sessions on an exercise bike, or squeezing a device that measures hand grip.
In both experiments swearing rudely led to significant improvements in performance compared with uttering "neutral" words.
The study followed up earlier work that showed how swearing increases pain tolerance.
Dr Richard Stephens, from the University of Keele, who led both teams, said: "Quite why it is that swearing has these effects on strength and pain tolerance remains to be discovered. We have yet to understand the power of swearing fully."
The findings were presented at the British Psychological Society's annual meeting.
